HYDRANT.

SPECIFICATION forming part of Letters Patent No. 278,435, dated May 29,1883.

To all whom it may concern Be itknown that I, WILLIAM KAISER, ofWilkes-Barre, in th'e'county of Lnzerne and State of Pennsylvania, haveinvented a new and useful Improvement in Hydrants, which improvement isfully set forth in the following specification, reference being bad tothe accompanying drawings.

This invention-relates to hydrants having stocks consisting of a cast orwrought iron tube ofsuch construction as to admit of repairing withoutdigging up the stock.

The invention will first be: described, and then designated in theclaims.

In the accompanying drawings, Figure 1 is a vertical section ofthe'hydrant, the lever cupying the position as when the valve is open.Fig. 2 is a transverse vertical section of thehydrant cap and levei',the latter being raised, as when. the valve is closed. Fig. 3 is asideview, large scale,of the screw-plug to which the lever is attached. Fig.at is aborical section of the lower end of hydrant-stock embracing thevalve-casing. Fig. 7 is a vertical section of the top part of stock,showing means for automatically closing the hydrantvalve. Fig. 8 is avertical section of the top part of a wheel-operated valve, as when thevalve is closed. This form is used for fire hydrants. V i

The letter-A designates the hydrant-stock, which may be an. ordinarywrought pipe; A, the cylindrical cast top of the hydrant; B, a capsurmountiug the cast top, provided with two parallel walls, c, united atone of their ends and bases, the latter forming the horizontal circularcap. A rim or flange, cl, projects downward from this cap and surroundsthe cast top A. Two or more holes are made in.theicap,-each for theinsertion of a bolt, d, which secures the cap to the top A. The interiorof thetwo vertical walls consists of two parallel faces with aspacebetween them. 'Each face has a circular curved channel or groove,

c, which are directly opposite each other, as seen in Figs.1 and 2. Thelever O has a segment-shaped inner end, f, the periphery of which isprovided on each side with a flangeor head, g, which curves to conformto the segment-shaped end of the lever. Each of these curved beadsoccupies one of the curved channels e, as seen in Fig. 2, wherein it mayslide.

It will thus be seen that the channels and beads which slide in themserve both as a pivot and hearing by which thelever, in order to open orclose the valve, may he moved from a horizontal to a vertical position,or vice versa. I prefer to make this cap and the two vertical walls ofone casting, as, if the walls are not integral-that is, of one piece-the re will be great difficulty in securing them side by side withsuch rigidity as to prevent their soon workingloose. The lever has apivotinghole for the pivot-bolt h. This hole is located eccentricallywith respect to the curved flanges on-the segment-shaped end. The effectof this arran'gementis that when the lever is depressed so as to causethe segment-shaped end to turn in its bearings (the channels 0) aquarter or less revolution the interior parts which connect with thevalve mechanism are raised vertically, thereby opening the valve, ashereinafter described, and permitting the water to A coiniecting-piece,which 1 term a screwplug, D, has two wings, 1, with a space between,which thepart of the lever having the pivoting-hole may occupy. Each ofthese wings has a horizontal slot, h, as plainly seen in Fig. 3, throughwhich the pivot-bolt h passes. This slot permits the pivot-bolt to moveback and forth in a horizontal plane as its position is. changed by theturning oi. the eccentric segment-shaped part, and thereby thedischarge-pipe F and the parts connected with it maintain a truevertical position when they are raised, and thus there isan avoidance ofall cramping or chafing ot' the parts ot' the valve mechanism at thelower end of the stock.

The T-connection E is suspended by the screwafterexplained,Aninward-projectingflange,'

k, is-formed within the lower end ofthe cast top, and serves as anabutment for the end of the stock. Ametal washer, I, is employed betweenthe flange and end of stock, the central hole in the washer serving as aguideor hearing for the vertically-movable discharge-pipe F. Thus themetal washerserves to keep these parts in true relation with respect toeach other, and by holding the discharge-pipe to an exact axial positionwhile it moves up and down the wear on the valve mechanism is reduced toa minimum. A set-screw, i, is provided in the base to secure the partsfirmly.

Perforatious 7c in the two vertical walls of the cap are of such size asWill permit the locking-bolt of a padlock orother locking device to passthrough, the insertion of which effectually prevents the lever (1passing the point of insertion, and thereby locks'the hydrant. This isdesirable where hydrants are placed in exposed positions or where theyare liable to be tampered with by children.

The vertical channel won the outer periphery of the movable water-way Lconstitutes the wasteway of the hydrant when the same is in a closedcondition, as shown in Fig. 6. Said channel extends from the lowerperforation, it, to and communicates with the perforation it, both invalve-hood N, the latter being opposite the outlet 1) in the case,thereby allowing all the water remaining in pipe F free egress orescape. After having finished the respective round portions of, to wit,the exr terior of movable water-way L, and the intebe of such thicknessas to closely fill the inside diameter of the circular portion ofvalve-hood N, thus serving as a packing between them, and prevents theescape of any water in that direction. Whenthehydrant is in process ofopening or open, as shown in Fig. 1.

The lowermost part of the valve-case U is provided with a nipple, V,having an outside screw-threadfor attachment to the service'- pipe orother source of supply. The inlet S for the water passes through thisnipple, and its upper side constitutes'a seat, against which the washert at the lower extremity ofthe movable water-way rests, as seen in Fig.6, to close the inlet. Side openingsfl', above the washer communicatethrough the movable water-way directly with the discharge-pipe F.

Fig. 7 illustrates a modification in which the channels or grooves inthe two walls of the cap are dispensed with. The angular part '9 of thelever, by resting on the plate 0 of the top, serves as a fulcrum bywhich the movable water-way is raised and the valve opened. Thiscompresses the spring a, the lower end [of which-abuts against a pipecouplingfor cally close the valve.

Upon releasing the handle the said spring will automati- The samevalve mechanism may have for an actuating device a screw-plug with ayoke, 2, instead of wings, connected to a screw-threaded bolt, 0,actuated by a hand-wheel, crank, or spanner applied to the headf. (SeeFig. 8.) If it is desired to make needed repairs of the interior workingparts,the operation necessaryis simply and only to loosen the set-screwz" from its hold-on stock A, and then turn the top A. This revolveshorizontally the moving waterway L, which, being squared at P, will turnthe valvehood N from the interior of easing U. The entire valvemechanism may then be drawn from the stock.

I will now proceed to describe the mode of operating my hydrant. Whenthe hydrant is. properly'attached to a water-supply and has I beenclosed, as shown in Figs. 2 and'6, the water remaining in pipe F willflow out the two openings into the casing U, thence will flow throughperforation a, channel w, and thenthrough perforation n in valve-hood N,and finally'escape through outlet p in the valvecasing. The valvemechanism being nowclosed to prevent water fromentering the inlet S, bydrawing the lever G from the position shown in Fig. 2 to that shown inFig. 1 the discharge-pipe F and movable water-way L will be raisedvertically, lifting the valvewasher t-from its seat, and at the sameinstant way it 'w n by the leather ring or washer q sliding over andcovering the lower perforation, 12, thus preventing the escape of anywater when the valve is open or while'it is be- "the movement ofwater-way L closes the waste I in g opened, and allowing free ingress ofwater into the casing U, and thence through waterway L, pipe F, anddischarge-nozzle.
